Description

A kind of Novel surgical needle nail combines inside-fixture

Technical field

The utility model relates to medical apparatus technical field, specially a kind of Novel surgical needle nail combines inside-fixture.

Background technique

In bone surgery, usually injured bone is fixed using Kirschner wire, helps bone quickly extensive with this It is multiple to cure.Such as application No. is a kind of Kirschner wires of CN201320417488.9, it includes needle body, and the needle body is equipped with and is linked as one The needle tip of body, needle tip are equipped with the first pin hole and the second pin hole of stringer arrangement, and the needle tip is flat fusiform.Above-mentioned gram Family name's needle needle tip can ligature hernical sac or vaginal process sharply without sharp for flat fusiform outside peritonaeum, and be Complete Ligation, no Gap is stayed, smaller to tissue damage, needle tip is equipped with the first pin hole and the second pin hole, avoids line and line and generates at pin hole and rubs Wipe, convenient and practical and economical and easily available during laparoscope ligation operation, the side of needle tip is in arcuation, convenient at peritonaeum into The free operation of row.

In bone surgery, the fixation of avulsion fracture, due to tendon, ligament drawing under, sclerite is frangible, reset after it is fixed Difficulty, postoperative easy generation fixation failure, drill bit sclerite fragmentation during drilling on sclerite or being screwed into screw increase Operation is difficult.And above-mentioned Kirschner wire is as common Kirschner wire, is used alone when there is fixed bone block, because of Kirschner wire stretching resistance Difference, the separation of Yi Fasheng sclerite, Kirschner wire loosen failure, so providing a kind of Novel surgical needle nail in conjunction with inside-fixture to solve The certainly above-mentioned problem very it is necessary to.

Summary of the invention

The purpose of this utility model is to provide a kind of Novel surgical needle nails to combine inside-fixture, to solve above-mentioned background The problem of being proposed in technology.

To achieve the above object, the utility model provides the following technical solutions: a kind of Novel surgical needle nail combination is interior solid Earnest, including shank and screw, described shank one end are fixedly connected with the first annulus, are fixedly connected with above the screw Second annulus, the screw are socketed on inside the first annulus, and screw is movably connected on inside the first annulus, the shank On be provided with open slot several groups, corresponding number designation is carved on the shank above the open slot.

Preferably, the shank other end is provided with cubic cone cell chamfering.

Preferably, the screw nail rod diameter is greater than in the first annulus less than the first internal radius, the second annulus outer diameter Diameter.

Preferably, the open slot is convex structure.

Preferably, the screw is cancellous bone screw or cortex bone screws.

Preferably, the shank is Nitinol bar, and first annulus and the second annulus are Nitinol annulus.

Compared with prior art, the utility model has the beneficial effects that a kind of Novel surgical needle nail knot of the utility model Inside-fixture is closed, structure novel enables to screw and shank to cooperate and bone is fixed, increases whole tensile capacity And fixed effect.It can be inserted at the tetragonal pyramid of shank tail portion and carry out skeletal fixation, wherein the setting of open slot is then easy for shank It is bent, number designation is then the distance for determining bending, and screw is inserted in inside the first annulus, and the screw used is pine Matter bone screws or cortex bone screws can be selected according to behaviour in service at that time, and screw hammers into bone, be increased The whole tensile capacity of shank is added.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-6 is please referred to, the utility model provides a kind of technical solution: a kind of interior fixation of Novel surgical needle nail combination Object, including shank 1 and screw 3, described 1 one end of shank are fixedly connected with the first annulus 2, fixed company above the screw 3 It is connected to the second annulus 4, wherein the connection type of the connection type and screw 3 of shank 1 and the first annulus 2 and the second annulus 4 It is laser welding, the screw 3 is socketed on inside the first annulus 2, and screw 3 is movably connected on inside the first annulus 2, It is provided with 5 several groups of open slot on the shank 1, is carved with corresponding number designation 6 on the shank 1 of 5 top of open slot, wherein The distance between open slot 5 be it is identical, can according to need, there is not distance between 1 upper open slot 5 of shank of different length Same length specification, can be 5mm, or 10mm is selected according to production and actual demand.

1 other end of shank is provided with cubic cone cell chamfering 7.The 3 bar diameter of screw is less than 2 internal diameter of the first annulus, institute 4 outer diameter of the second annulus is stated, 2 internal diameter of the first annulus is greater than.The open slot 5 is convex structure.The screw 3 is cancellous bone Screw or cortex bone screws.The shank 1 is that Nitinol bar, first annulus 2 and the second annulus 4 close for NiTi Golden annulus.

Working principle: a kind of Novel surgical needle nail of the utility model combines inside-fixture, and structure novel enables to spiral shell Bone is fixed in adjusting screw 3 and the cooperation of shank 1, increases whole tensile capacity and fixed effect.The tetragonal pyramid of 1 tail portion of shank Place, which can be inserted into, carries out skeletal fixation, and the wherein setting of open slot 5 is then easy for shank 1 and is bent, and number designation 6 is then determining The distance of bending is inserted in screw 3 inside first annulus 2, and the screw 3 used is cancellous bone screw or cortex murices Adjusting screw can be selected according to behaviour in service at that time, and screw 3 hammers into bone, increase the whole tension energy of shank 1 Power.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
